Re: IBIS MOdel Question

Make sure that:

1. The curves are continuous
2. The ramps (if any) cover the whole switching range
3. All pins are assigned to models

These are the three worst problems I've run into trying
to use IBIS models supplied by well-known parts vendors.

If you have access to one of the commercially available
signal integrity tools, try actually using the model
with it. Your customers will thank you if you actually
make your model work in the simulators they are going
to use!
